IMPROVEMENT IN GRAIN-BINDING MACHINES.

Specification forming part of Letters Patent No. 28,338, dated May 22,1860.

To all whom it may concern Be it known that I, D. W. AYRES, ofMiddleport, in the county of Iroquois and State of Illinois, haveinvented a new and Improved Grain-Binding Attachment for Reapers; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in w.hich-' Figure l is atransverse vertical section of my invention, taken in the line a a, Fig.3; Fig. 2, a section of my invention, taken in the liney 3 Fig. 1; Fig.3, a plan or top view of my invention; Figs. 4 and 5, detached views ofportions of my invention; Fig. 6, a section of a portion of myinvention, taken in the line 2 2, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in the employment or use of a rotating arm,stationary gavel-receiving box, twisting device cutter, and holder, andfingers or teeth, all arranged substantially as hereinafter fully shownand described, whereby the gavels may be bound, and the binding-wiretwisted and cut and secured in proper position for a succeedingoperation, all the parts working automatically by the turning of asingle shaft, and a gavel bound at each revolution of said shaft.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the platform of an ordinary reaper, and B is ahollow shaft,which is fitted in a proper bearing, a,,on the framing of the platform.To the inner end of the shaft B a circular disk, 0, is attached, saiddisk having an arm, D, projecting horizontally from it at its periphery,as shown clearly in Figs. 2 and 3. To the end of the arm D a gearedsegment, E, is attached, the faceside of which, below its teeth, I has acurved slot, 0, made in it, as 4 rod or bar thrust out from the arm D.(See more particularly Fig. 1.)

G is a semi-cylindrical box, which is secured in a permanent positionconcentrically with the disk 0, and has three curved teeth or fingers,g, at its front end, said teeth or fingers being secured to a rod, h,which is allowed to turn in a bearing on the box G. One end of the rod his bent at rightgangles to the other part, as shown at h, and said bentpart extends within the space between the disk 0 and the end of box G,and within the path of rotation of a pin, 2', attached to disk 0.

To the framing of the platform A, and at a point opposite the upper endof the box G, there is secured a bearing, H, in which a twister, I, issecured. This twister is formed of two parts, one part being comprisedof a cylinder or arbor, J, with a semicircular head, It, and the otherpart being comprised of a similar semicircular head, l, attached to ashank, m, which is pivoted in the arbor j, as shown at n, Fig. 5. Thestraight edges of heads 10 and L are opposite or face each other, and bymoving shank m the straight edges of the heads may be entirely closed.This moving of shank m is performed in a way hereinafter shown.

To one side of the bearing H a hooked or bent bar, J, is attached by apivot, n, the outer end of said bar passing into an opening, 0, in thebearing H, opposite the upper end of the shank m of the twister I. Tothe same side of the bearing H there is attached a lever, K, which formsa cutter and holder for the wire, said lever performing the function ofa cutter in consequence of a cutting projection, p, at its under side,and the function of a holder in consequence of tooth-like projections,g, adjoining the cutter. (See Fig. 4.) The lever K has a pin, 0',projecting horizontally from it, the object of which will be presentlyshown.

The upper end of the arbor j of the twister has a pinion, s, on it, saidpinion being within the path of rotation of the segment E, and the lowerpart of the bearing H has two projecting ends, t t, which are nearly inline with the bar or rod. To the framing of the platform A, and directlyopposite the outer end of the hollow shaft B, there is placed a wheel,L, on

which the wire M is wound that is used for binding the gavels.-

The operation is as follows The wire M is passed through the hollowshaft B, through the disk 0 in a straight or radial direction, andthrough the arm D, and then through an eye in the outer end of the rodor bar F. At the commencement of the operation the at tendant places theend of the wire under the holding-teeth g of the lever K, the spring aof said lever causing the wire to be firmly held. The fingers g areturned outward and fit in recesses in the platform, and the gavel to bebound is raked on them toward the box arm D. The rod or bar F conductsthe wire between the projecting ends t t of bearing H,

and causes the same to pass down between the heads k I. It will beunderstood that'the wire now encompasses the gavcl,and that both ends ofthe-wire are between the heads 70 I, as

the end first secured by the lever K passed between the heads as the armD first rotated. The face of the segment E now strikes the'bent bar J,and causes the latter to bear against the shank m of the head 1, closingthe same I and causing the ends of the wire to be firmly grasped. Therod or bar F then carries the wire under the lever K, and the pin 1', asthe segment and arm D move, passes into the groove 0, which aetuateslever K, and causes the wire to be cut; the teeth q retain the end,however, for a succeeding'revolution of the arm D. At this instant theteeth b of the segment E engage with the pinion s, and the heads k l arerotated, making one revolution, and thereby securing the wire around thegavel. The gavel or sheaf is then removed from box G endwise, asindicated by arrow 2?, and the succeeding operation follows.

The shaft B and arm 1) may be rotated manually, the wire being drawnfrom the wheel L by therotation of the arm D, or they may be operatedfrom the driving'w-heel or other working parts of the machine.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is I The employment or use of the rotating armD with the toothed segment E and rod or bar F attached, in connectionwith the stationary box G, the twisterformed of the stationary andmovable heads is l, and the holder and cutter formed of the lever K,provided with cutting and holding teeth 11 and q, all being arrangedfor' joint operation, substantially as and for the purpose set forth.
